.arrlicaaon med Tune a2, 1925'- Sefa Nl" 38872 l l i u V'llhis inventionrelates to car Wall constructions and particularly to that type inwhich' the wall comprises ribbed or panelled me? tallic sheets. Whilesuch constructions are particularly applicable to car ends lthey `may bealso eiiectually employed as the side walls ofthecar.

An object of the invention is to produce wall sheets of this characterwithiribs *or panels pressed therein, the conformation otv which isdesigned to impart the -greatest rigidity and strength to the sheets.Other objectsof` the invention, aslwellasthe novel details ofconstruction ot the same. will be made more apparentes this descriptionproceeds, especially when considered in connection with the accompanyingdrawings where- Figure 1 is an elevation of a car end constructed inaccordancewitlh this inventiom Figure 2 isa sectional View takensubstantially on the plane indicatedbyline 2--2ofFigureL Figure 8 is asectional rViewV taken subplane indicated byline 3-`3 in Figure 1, i

Figure 4 is a similar section-showing a modiiied form 'of construction,

Figure 5 is a similar section showing;n still another modified torm otconstruction, and

Figure 6 is a fragmentary elevational View showing a modied form ot ribconformation. f

While the invention is herein illustrated and described in connectionwith car ends it will be immediately apparent that it is equallyadaptable to all car wall constructions. ln the drawings a ear end isillustrated and is shown as comprising a plurality .of sheet metalplates 10.A the adiacfirti` longitudinal edges 11 ot' which are arrangedin overlapping relation and are suitably apertured and secured togetheras by means of rivets 12. Each sheet is preferably formed with laterallyextending tiannes 13 to facilitate attachment ot the sheets to the sidewalls ot the can-thc upper and lower sheets being also suitably attached'respectively to the trame members la and y15 yoi' the car.

Each sheet is formed with a. plurality of panels 16 arranged in spacedplanes parallel to the'marginal portions 11 of thesheet, these panelsbeing connected to the remainder ofthe sheet byfoblique portions `17 andsubstantiallyV right-angular portions 18, these panels 16 together withthe connecting portions 1'?l and 18 constituting ribs which 'areformedby suitably pressing the metal plates 10. In tormingthe ribs to Vproducethe panelportion 16 inclined portions` 19 are yformed at the end thereofwhich connect the panels'to the main portion of the sheetfthese inclined`portions 19 being substantially triangular and Hat and angularlydisposed with reference` to the portions 17 and `1S.

` In `Figure 4 `a slightly modified form of constructi on is illustratedin which the sheets to, vwhilefthe` lower sheet 10 is shown as formedintegrally vwith `the 'bottom frame Amember 15.

"In lFigure `dst-ill vanother modification is illustrated in which aplurality of' sheets 10 are illustrated, these sheets beine' of a lesserwidth than those/shown in the first described torni. whereby a ,greaternumber are employed informing the car end. The lowermost sheet is shownas connected to a frame member 15, here shown as a channel bar.

ln Figure 6 the rib is shown as formed with a diiterent endconstruction.y the panel 16 being connected to the main part of thesheet by means ot' an inclined portion 19 rounded with reference to theportions 17" and 18.

l'n a car wall construction of the character herein described a greaterstrength. rigidity and durability is obtained owing to the peculiarconformation ot the ribs, a plurality of which are formed in each ot thesheets constituting the wall. panel portions 16. which are parallel tobut spaced from the plane of the main sheet and lthe marginal portionsthereof, are joined` on the one hand.l by the inclined portions 17 andon the other hand, by the right-angularly arranged portions 18. Thecomposite sheet constitutingf the wall and' comprising a plurality ofthe sheets 10 rigidly united alongV their overlapping longitudinal edgesconstitutes a strongly trussed structure, one which is inherently rigidand capable of withstanding unusually heavy lateral stresses.

As shown in the preferred and modilied ormsof construction hereinillustrated, the Sheets L10. may be formed of any desired width, thewidth of the individual sheets', however, determining the number ofsheets required in a given wall area.A By forming the wall structure ofaplurality of separate sheets repair may be made to any damaged portionthereof Without necessitating the destruction of the entire wall.Consequently sheets 10 of relatively narrow Width are more efficient andpreferable.: Furthermore, as shown in the forms of the invention hereinillustrated, the upper and 'lower sheets of the wall maybe connected toor formed integral with the upper and lower frame members of the car.

While several forms of the invention have been illustrated herein, itwill be readily apparent to those skilled in the art that various other'forms and modiications of the invention may he resorted to withoutdeparting 4from the spirit and scope of thc invention. land'to this endreservation is made to make such changes as may come Within the purviewo the accompanying claims. i

What I claim als my invent-ion is:

1. In a car wall construction, a sheet metal plate pressed to forma ribextending longitudinally of the plate, each rib havin a portionparallel, a portion inclined, an a portion at right angles to the planekof the plate, the saidf right angularly arrangedportion 'terminating 1nthe planeof the plate. f 2. In a car wall construction, a plurality -ofsheet metal plates having overlappingadwhich are similarl jacent edgeportions riveted to each other, each plate being pressed to form a ribextending longitudinally of the plate, each rib having a portionparallel, a portion inclined and a portion at right angles to the planeof the plate said two latter portions merging into the plane of theplate.

3. In a car wall construction, a sheet metal plate pressed to form aplurality of spaced parallel ribs, corresponding portions of arranged,each rib having a portion para lel, a portion oblique, and a portion atright angles to the plane of the plate.

4. In a car wall construction, a sheet metal plate pressed to form aplurality of corre,- spondingly shaped ribs, each rib having portionsoblique and at rightl angles to and merging into the plane of the plate.

5. In a carl wall construction, a sheet metal plate pressed to form aplurality of correspondingly' shaped ribs, each rib having a portionoblique, and a portion at right angles to the marginal plane of theplate, said portions beingarranged in spaced parallel relation.

6. A car wall construction comprising a 'f1' plurality of sheet-,metalplates with their longitudinal edges arranged horizontally and inoverlappin relation and riveted to each other, each p ate being pressedto form a panel parallel to the marginal portion of the :t:

plate, a portion at right angles to the plane of the plate connectingone longitudinal edge of said panel to said plate and a portion inclinedto the lane of the plate connecting the other longitudinal edge of saidpanel to said plate.

In testimony whereof I aiiix my signature.

ALFRED R. WILSON.
